I just went out to my truck and looked. The brake booster line is definatly easier to access and a better location to use. Same concept except from that location is 100% better.

I found my leak. Looks to be leaking from the farthest 2 exhaust flanges. The 5th is missing one bolt altogether, and the 6th has a good gap between the manifold and the block. This isn't a fix I really want to try to tackle, and I don't think it's a wise idea to try and tighten it either. Guess ill live with the noise until it gets really bad. At least it's not a crack...yet. Would anyone recommend an exhaust weld paste to bead around the gasket?
